Excerpts from:The Iceman’s Axe:
Texture applied to Archaeometallurgy
Seminar at CMU, April 2005 by:G. Artioli
Università degli Studi di MilanoDipartimento di Scienze della Terra
[Department of Earth Sciences,Milan University for Study]
Ötzi ~ 3200 B.C.
Iceman/Ötzi
Iceman axe (Ötzi)
blade
body
Note the lack of texture
Lovere LOV-330
By contrast with the Ötzi Iceman’s Axe, this axe was worked.
Summary
• X-ray diffraction (and fluorescence) experiments are a very useful probe of materials and their history.
• For historical artifacts, non-destructive techniques are often a requirement.
• Synchrotron radiation with large penetration depths permits large objects to be examined without removing samples.
• Sophisticated metal-processing technology is surprisingly old!
